  • Air Pressure Effects The Speed Of Falling Objects
    1,498 words
    Research An object that is falling through the atmosphere is subjected to two external forces. The first force is the gravitational force, expressed as the weight of the object. The weight equation which is weight (W) = mass (M) x gravitational acceleration (A) which is 9. 8 meters per square second on the surface of the earth. The gravitational acceleration decreases with the square of the distance from the center of the earth. If the object were falling in a vacuum, this would be the only for...
  • Mixer And Nozzle Process Description
    784 words
    Mixer The hot air that is forced out of the combustor and through the turbine continues to exit the engine at the rearward. Before exiting however, this air must be mixed with the cooler bypass air that did not go through the compressor and combustor. These two air streams are mixed in order to quiet the engine. To understand how air can create noise, first consider the way water splashes and makes noise when a wave crashes. In the same way, when two different air streams traveling at extremely...

Local winds blow from any direction and usually cover short distances. Global winds blow from a specific direction and almost always cover longer distances than local winds. Both local winds and global winds are caused by differences in air pressure due to unequal heating of the atmosphere. During the day, the air over a land area is often warmer t...

    Using an electric hybrid leads to a significant improvement in vehicle fuel economy. Unfortunately, it also leads to a substantial increase in cost. Regenerative compression braking offers another way to achieving the same objective without incurring the same cost penalty. With some modifications, the vehicle engine can perform both absorption and recovery of braking energy, using compressed air for energy storage. The process parallels the one employed by electric hybrids, but it requires none ...
